Petra

Petra is a historical and archaeological city in the Jordanian governorate of Ma'an that is famous for its rock cut architecture and water conduits system. Established sometime around the 6th century BC as the capital city of the Nabataeans. Located amid rugged desert canyons and mountains in what is now the southwestern corner of the Hashemite Kingdom of Jordan, Petra was once a thriving trading center. The city sat empty and in near ruin for centuries. Only in the early 1800s did a European traveler disguise himself in Bedouin costume and infiltrate the mysterious locale.

In 1985, the Petra Archaeological Park was declared a UNESCO World Heritage site, and in 2007 it was named one of the new seven wonders of the world. Petra was chosen by the BBC as one of "the 40 places you have to see before you die"
